Note 1) The detector uses a 12-bit absolute encoder 1024 P/R.
2) Type “A” indicates 200 V specification, and type “B” indicates 100 V specification.
3) “A3A(B)W14B”, “A3A(B)W16B”, “A5A(B)W14B”, “A5A(B)W16B”, “01A(B)W14B” and
“01A(B)W16B” have a keyed shaft. The keyway complies with JIS B 1301-1976 (preci-
sion). A straight key is supplied.
4) The quoted allowable radial load is the value at a position 20 mm (0.79 in.) from the mo-
tor mounting surface.
5) The electromagnetic brake is only to hold the load in position and cannot be used to stop
the motor.
